INSTALLATION and OPERATING INSTRUCTIONS
EQUIPMENT SELECTION
LOCATING THE FURNACE
An accurate heating load calculation must be conducted
using American Society of Heating, Refrigeration and
Air Conditioning Engineers (ASHRAE) or Air
Conditioning Contractors of America (ACCA)
manuals. Do not add a large safety factor above the
calculated value. If the calculated heating load
requirement exceeds the heating capacity rating of a
given model, use only the next larger size available.
Never increase by any more than absolutely necessary
based upon available equipment heating capacities.
Always select based upon heat capacity (output), never
use input capacities.
When installing the furnace be sure to provide adequate
space for easy service and maintenance. Locate the
furnace as close to the chimney as practical, giving
consideration to the accessibility of the oil burner,
controls, and blower for service. Allow a minimum of
24 inches at front of furnace for servicing oil burner.
Allow adequate room for filter and blower
maintenance. Clearance from combustible material as
stated on the furnace and repeated in Table 1 must be
maintained. For damp basement installations, a raised
concrete pad is recommended. This will help keep the
bottom of the furnace dry and reduce the risk of rusting.
NOTE: It is the personal responsibility and obligation
of the purchaser to contract a qualified
installer to assure that installation is adequate
and is in conformance with governing codes
and ordinances.
An oil burner must have a generous supply of
combustion air to operate properly. The flow of
combustion and ventilating air must not be obstructed
from reaching the furnace. See “Combustion Air
Requirements” section.
The furnace area must be kept clear and free of
combustible materials, gasoline and other flammable
vapors and liquids.
This unit is not designed for mobile home or trailer
installations. Always install furnace in a level position.

INSTALLING THE FURNACE
DUCT WORK
INSTRUMENTS REQUIRED FOR PROPER
SETUP OF THE FURNACE
The air distribution system should be designed and
installed in conformance with manuals published by
Air Conditioning Contractors of America (ACCA) as
set forth in Manual D, or ASHRAE publications.
It is important that a set of instruments capable of the
following requirements be used for the setup of this
furnace to ensure proper and safe operation:
1. Oil pump pressure gauge that measures up to
150 PSI.
2. Smoke gun to pull smoke samples from flue.
3. Draft gauge that will measure -.02" water column
(W.C.)
4. Duct static pressure gauge 0-1.0" W.C. range.
5. Temperature gauge that can read from 50° F up to
700° F.
IMPORTANT
When a furnace is installed so that supply
ducts carry air circulated by the furnace to
areas outside the space containing the
furnace, the return air must also be handled
by a duct(s) sealed to the furnace casing and
terminating outside the space containing the
furnace This is to prevent drawing possible
hazardous combustion products into the
circulated air.
6. A gauge to measure CO2 or O2.
INSTALLATION
A typical installation is shown in Figures 4 and 5. All
parts of the furnace installation (furnace, oil tank and
piping systems, combustion and ventilation air, venting,
etc.) must comply with NFPA31, Installation of Oil
Burning Equipment -- latest edition. This drawing
shows the typical connecting parts needed to correctly
install this furnace. Make sure that all parts of the
heating system comply with the local codes.
Check the furnace and your load calculation to verify
that the unit is properly sized. (Refer to “Equipment
Selection” section on Page 4.)
The correct size of unit needed may be substantially
smaller than the unit being replaced due to home
improvements and technology advancements since the
initial installation.
INADEQUATE SUPPLY AIR and/or RETURN
AIR DUCT SYSTEMS
Short cycling because of limit control operation can be
created by incorrectly designed or installed supply and/
or return air duct systems.
The duct systems must be designed using ASHRAE or
ACCA design manuals and the equipment CFM and
external static pressure ratings to ensure proper air
delivery capabilities.
On replacement installations, particularly if equipment
is oversized, the duct systems can easily be undersized.
Modifications may be required to assure that the
equipment is operating within the approved
temperature rise range when under full rated input
conditions, and that no short cycling on limit controls is
occurring.
Manual 2100-540D
Page
8 of 45
INSTALLING A COOLING UNIT
When the furnace is used in connection with a cooling
unit*, the furnace shall be installed parallel with or on
the upstream side of the cooling unit to avoid
condensation in the heating element. With a parallel
flow arrangement, the dampers or other means used to
control flow of air shall be adequate to prevent chilled
air from entering the furnace, and if manually operated,
must be equipped with means to prevent operation of
either unit, unless the damper is in the full heat or cool
position.
* A cooling unit is an air conditioning coil, heat
pump coil or chilled water coil.
When installing a cooling unit above an FH or FL
(below on an FC) series furnace, the coil must be
spaced far enough from the furnace outlet to assure
proper operation of the furnace. Bard supplied coils,
when used with Bard supplied coil cabinets, are
automatically positioned.
For top discharge FH and FL models, when coils are
installed without using Bard coil cabinets or coils of
another brand are used, the coil drain pan should be
located a minimum of four (4) inches above the top of
the furnace cabinet. If a greater clearance is specified
by the coil manufacturer then it would apply.
NOTE: IF DRAIN PAN IS ANYTHING OTHER
THAN A STEEL PAN PARTICULAR
ATTENTION MUST BE GIVEN TO THE
INSTALLATION INSTRUCTIONS FOR
THE COIL TO MAKE SURE IT IS
ACCEPTABLE FOR USE WITH THESE
OIL FURNACES HAVING MAXIMUM
OUTLET AIR TEMPERATURE OF 200° F.
See Cooling Tap Select Table D (Page 19) for CFM at
static pressures for additional information.
WIRING
FIELD WIRING
FACTORY WIRING
All wiring must conform to the National Electrical
Code and all local codes. A separate fuse or breaker
should be used for the furnace.
All units are fully factory wired. Multispeed blowers
are factory wired on high speed for cooling/manual fan
operation. Heating speeds are wired for the largest
input and may need lower speed for field installed low
input nozzle. If replacement wire is necessary, use 105
degrees C minimum. See electrical data, Table 3.

OIL LINE PIPING
BECKETT AFG OR NX OIL BURNER
First determine whether the pipe system is to be a
single line system or a two line system. All
connections must be absolutely air tight or you will
have a malfunction of the burner. When installing the
piping, a good oil filter should be installed close to the
burner. A single line system is recommended for
gravity feed.
This furnace is equipped with a high static Beckett AFG
or Beckett NX oil burner which is designed to produce
adequate draft in nearly any vertically vented
application. The burner employs the latest time tested
controls of the highest quality. The controls consist of a
high voltage Beckett solid state igniter, a Beckett
“CleanCut” oil pump with an integral solenoid valve,
and a Genisys 7505 primary control.
A typical single inside tank installations shown in
Figure 6. For installation details for this and other tank
configurations, refer to NFPA31 -- latest edition. All
tank and pipe setups must comply with NFPA31.

These controls were selected for their proven high
quality, dependability, and serviceability. With proper
maintenance this burner assembly will provide many
years of reliable service.
All units are shipped with the oil burner installed, and
with high rate oil nozzle installed designed for use with
No. 1 or No. 2 fuel oil. Inspect firepot refractory
before firing to be sure it has not been jarred out of
position in shipment. Burner air tube must not
extend beyond inside surface of firepot. Burner
head should be centered on the combustion chamber
opening.
BECKETT SOLID STATE IGNITER
This igniter differs from the traditional iron core
transformer in that it produces a 14,000 volt spark
instead of a 10,000 volt spark of the iron core
transformer. This hotter spark provides for cleaner,
faster ignitions. Being solid state technology this
igniter is less susceptible to problems caused by voltage
variations. It also has a greater ability to ignite cold
and/or inconsistent oil. The solid state igniter is wired
to the primary control the same as an iron core
transformer.
GENISYS 7505 PRIMARY CONTROL
WARNING
Never attempt to use gasoline in your
furnace. Gasoline is more combustible than
fuel oil and could result in a serious explosion
causing damage, injury or death.
The following is a detailed explanation of each control
included in the Beckett AFG Oil Burner, how each
operates, how to set up the burner, and how to
troubleshoot problems should they occur.
The Genisys 7505 Interrupted Electronic Oil Primary is
a line voltage, safety rated, interrupted ignition oil
primary control for residential oil burners. The Genisys
7505 used with a cad cell flame sensor, operates the oil
burner and oil valve. The primary controls fuel oil,
senses flame, controls ignition spark and is designed to
notify a remote alarm circuit before going into lockout
when equipped with a flame monitoring system.
This primary control possesses the latest technology, is
a very simple control to operate and provides additional
troubleshooting features to ease service and reduce
down time. The operational guide for the Genisys 7505
primary control is provided following on Page 14.
BECKETT “CLEANCUT” OIL PUMP
This oil pump is equipped with an oil solenoid valve
installed in the pump housing. This feature provides
quick cutoffs resulting in reduction in smoke after the
burner shuts down. This is a time proven pump design
and is capable of both one and two pipe systems. All
installation and set up instructions are outlined in the
“Oil Pump Specification” section of the installation
instructions manual.

PRIMARY OPERATIONAL GUIDE
BECKETT GENISYS 7505
Sequence of Operation
If the control locks out three times without
completing a successful call for heat, the control
enters Restricted (Hard) Lockout, and must be reset
by a technician. Hold the reset button for 15
seconds until the red light shuts off to reset from
Restricted Lockout.
5. Ignition Carryover: Once flame is established,
the igniter remains on for 10 additional seconds
to ensure flame stability.
6. Run: The flame is sustained until the call for
heat is satisfied. The burner is then sent to
Motor-Off Delay (Postpurge), if applicable, or it
is shut down and sent to Standby.
BURNER STATES
1. Standby: The burner is idle, waiting for a call
for heat.
2. Valve-On Delay (Prepurge): The igniter and
motor are on while the control delays turning on
the oil solenoid valve for the programmed time.
3. Trial for Ignition: The fuel valve is opened. A
flame should be established within the factory
set trial for ignition time (“lockout time”).
4. Lockout: The control has shut the burner down
for one of the following safety reasons:
•
The trial for ignition (lockout) time expires
without flame being established.
•
The cad cell detects flame during Valve-On
Delay.
•
The Recycle mode 30-second time budget
expires (see “Recycle” section for complete
explanation of recycle time budget).
Manual 2100-540D
Page
14 of 45
7. Recycle: If the flame is lost while the burner is
firing, the control shuts down the burner, enters
a 60-second recycle delay and then repeats the
ignition sequence. The control will continue to
Recycle each time the flame is lost until the
accumulated oil-flow-without-flame time
reaches 30 seconds, at which point the control
will go into lockout. This feature prevents
excessive accumulation of oil in the appliance
firing chamber.
8. Motor-Off Delay: If applicable, the fuel valve is
closed and the control delays turning the motor
off for the set motor-off delay time before the
control returns to standby.
9. Pump Prime: The igniter and motor are on with
the oil valve open for up to 4 minutes. During
Pump Prime mode, the cad cell is disregarded,
allowing the technician to prime the pump
without having to jumper the cad cell.

PRIMING THE PUMP
WARNING
Hot Gas Puff-Back & Heavy Smoke Hazard
Failure to bleed the pump properly could
result in unstable combustion, hot gas puffback and heavy smoke.
•
Do not allow oil to spray into a hot combustion
chamber while bleeding air from the pump.
•
Install a gauge in the nozzle discharge port
tubing or fully open the pump bleed valve to
prevent oil spray from accumulating in the
combustion chamber during the air bleed
procedure.
•
Ensure that all bubbles and froth are purged
from the oil supply system before tightening the
pump air bleed valve.
1. Prepare the burner for priming by fully opening
the pump bleed port and attaching a clear
plastic hose over the bleed port fitting. Use a
suitable container to collect purged oil.
2. Initiate a call for heat.
3. After the burner starts, press and hold the reset
button for 15 seconds until the yellow LED
turns on. This indicates that the button has
been held long enough.
4. Release the reset button. The yellow LED will
turn off and the burner will start up again.
Manual 2100-540D
Page
16 of 45
5. At burner start up, tap the reset button within
the first 10 seconds of the ignition cycle. This
will transition the control to a dedicated Pump
Prime mode, during which the motor, igniter
and valve are powered for four minutes. The
yellow LED will be on.
6. Bleed the pump until all froth and bubbles are
purged. If desired, hold the reset button for at
least one second to exit Pump Prime mode and
return to Standby.
7. At the end of 4 minutes, the yellow LED will
turn off and the control will automatically return
to standby mode.
8. If prime is not established during the four
minute pump prime mode, return to step 5 to
re-enter Pump Prime mode. Repeat steps 5
through 7 until the pump is fully primed and the
oil is free of bubbles.
9. Terminate the call for heat, and the control will
resume normal operation.
CAD CELL RESISTANCE INDICATOR
• During the burner Run state, tap the reset button
(less than 1 second) to check the cad cell
resistance range. The yellow LED will flash 1 to 4
times depending on the amount of light detected
by the cad cell. See chart below:

RESETTING FROM RESTRICTED LOCKOUT
• If the control locks out three times without a
satisfied call for heat, or due to other significant
events such as a relay contact weld, the Lockout
becomes restricted in order to prevent repetitious
resetting by the homeowner.
Electronic Blower Control Interface
This furnace is equipped with an Electronic Blower
Control Interface, which through its set points
determines what the blower does with the 24 VAC
inputs from the home thermostat.
There are dip switches that control the ECM motor for:
CAUTION
Before resetting the control from restricted
lockout state, troubleshoot the heating
system for the root cause(s) of lockout and
make necessary repairs or adjustment to
ensure a safe start condition.
• Then, to reset, hold the button down for 15
seconds until the red light turns off and the yellow
LED turns on. Observe at least one full control
sequence of operation from startup to shutdown.
Simulate a flame failure lockout by following the
procedure (within this manual). If the operation is
erratic, or not to specifications, then replace the
control. Always verify the control functions
according to all specifications before leaving the
installation site.

• Any time the burner is running, press and hold the
reset button to disable the burner. The burner will
remain off as long as the button is held.
Burner Option – Flame Quality Monitor
This control is trained to recognize and remember a
good flame based on initial burner set up. Control
then monitors the flame via the CAD cell signal for
deviation in the combustion characteristics of the
burner. If the control senses a deviation on the high
side or on the low side from the original set up
condition for three consecutive cycles, it will trigger
an alarm circuit which can be tied to an audible local
device to signal the home owner or into the home
security system. Upon being notified of the alarm,
the security agency will notify the dealer of choice
based upon information supplied by the home
owner. The system will also be capable of being
connected to a phone line that will contact the dealer
directly with the alarm. This alarm will typically
sound 3 to 5 days prior to the primary control going
into lockout giving the service agency a prior notice
before a sooting condition or other failure can occur
resulting in untold savings. This monitor system is
available through your local distributor under the
Honeywell Part #QS7100F.

TROUBLESHOOTING GE ECM™ MOTORS CONT’D.
Replacing ECM Control Module
To replace the control module for the GE variable-speed indoor blower
motor you need to take the following steps:
1. You MUST have the correct replacement module. The controls are
factory programmed for specific operating modes. Even though they look
alike, different modules may have completely different functionality.
USING THE WRONG CONTROL MODULE VOIDS ALL PRODUCT
WARRANTIES AND MAY PRODUCE UNEXPECTED RESULTS.
2. Begin by removing AC power from the unit being serviced. DO NOT
WORK ON THE MOTOR WITH AC POWER APPLIED. To avoid
electric shock from the motor’s capacitors, disconnect power and wait at
least 5 minutes before opening motor.
3. It is not necessary to remove the motor from the blower assembly, nor
the blower assembly from the unit. Unplug the two cable connectors to the
motor control assembly. There are latches on each connector. DO NOT
PULL ON THE WIRES. The plugs remove easily when properly
released.
4. Locate the screws that retain to the motor control bracket to the
sheet metal of the unit and remove them. Remove two (2) nuts that
retain the control to the bracket and then remove two (2) nuts that
retain sheet metal motor control end plate. Refer to Figure 8.
5. Disconnect the three (3) wires interior of the motor control by
using your thumb and forefinger squeezing the latch tab and the
opposite side of the connector plug, gently pulling the connector. DO
NOT PULL ON THE WIRES, GRIP THE PLUG ONLY. Refer to
Figure 8.
6. The control module is now completely detached from the motor.
Verify with a standard ohmmeter that the resistance from each motor
lead (in the motor plug just removed) to the motor shell is >100K
ohms. Refer to Figure 9. (Measure to unpainted motor end plate.) If
any motor lead fails this test, do not proceed to install the control
module. THE MOTOR IS DEFECTIVE AND MUST BE
REPLACED. Installing the new control module will cause it to fail
also.
7. Verify that the replacement control is correct for your
application. Refer to the manufacturer's authorized replacement list.
USING THE WRONG CONTROL WILL RESULT IN
IMPROPER OR NO BLOWER OPERATION. Orient the control
module so that the 3-wire motor plug can be inserted into the socket in
the control. Carefully insert the plug and press it into the socket until
it latches. A SLIGHT CLICK WILL BE HEARD WHEN
PROPERLY INSERTED.
8. Reverse the steps #5, 4, 3 to reconnect the motor control to the
motor wires, securing the motor control cover plate, mounting the
control to the bracket, and mounting the motor control bracket back
into the unit. MAKE SURE THE ORIENTATION YOU SELECT
FOR REPLACING THE CONTROL ASSURES THE
CONTROL'S CABLE CONNECTORS WILL BE LOCATED
DOWNWARD IN THE APPLICATION SO THAT WATER
CANNOT RUN DOWN THE CABLES AND INTO THE
CONTROL. DO NOT OVERTIGHTEN THE BOLTS.
9. Plug the 16-pin control plug into the motor. The plug is keyed.
Make sure the connector is properly seated and latched.
10. Plug the 5-pin power connector into the motor. Even though
the plug is keyed, OBSERVE THE PROPER ORIENTATION. DO
NOT FORCE THE CONNECTOR. It plugs in very easily when
properly oriented. REVERSING THIS PLUG WILL CAUSE
IMMEDIATE FAILURE OF THE CONTROL MODULE.
11. Final installation check. Make sure the motor is installed as follows:
a. Motor connectors should be oriented between the 4 o’clock
and 8 o’clock positions when the control is positioned in its
final location and orientation.
b.Add a drip loop to the cables so that water cannot enter the
motor by draining down the cables. Refer to Figure 10.
The installation is now complete. Reapply the AC power to the
HVAC equipment and verify that the new motor control module is
working properly. Follow the manufacturer's procedures for
disposition of the old control module.

BURNER SETUP AND ADJUSTMENT
PROCEDURES
All oil burner installations should be performed by a
qualified installer in accordance with regulations of the
National Fire Protection Standard for Oil-Burning
Equipment, NFPA31 -- latest edition, and in complete
compliance with all local codes and authorities having
jurisdiction. A qualified installer is an individual or
agency who is responsible for the installation and
adjustments of the heating equipment and who is
properly licensed and experienced to install oil-burning
equipment in accordance with all codes and ordinances.
The proper installation and adjustment of any oil burner
requires technical knowledge and the use of combustion
test instruments. The following procedure must be
followed to correctly adjust the burner to match the
specific characteristics of the installation.
Manual 2100-540D
Page
24 of 45
IMPORTANT
Always use combustion test instruments when
making burner adjustments and draft gauge
when setting the barometric damper. It is
virtually impossible to make accurate and
reliable adjustments using the “eyeball” method.
Check all oil lines and connections for leaks.
Connect pressure gauge by removing bleed fitting and
screwing in pressure gauge. See Figure 12.
1. PREPARATION STEPS
A. Calibrate and Check Operation of
Measuring Equipment Follow
manufacturer’s recommended procedures for
calibration and equipment check out.
B. Prepare Heating Unit for Testing Drill two
1/4 inch holes in the flue between the heating
plant and the barometric draft regulator. If
space permits, the holes should be located in a
straight section of the flue, at least two flue
diameters from the elbow in the flue pipe and
at least one diameter from the draft regulator.
The purpose of the two holes in the flue pipe is
to speed up testing and reduce instrument
handling.
C. Clean and Seal Heating Plant Make sure the
burner blast tube, fan housing, and blower
wheel are clear of dirt and lint. Seal any air
leaks into the combustion chamber.
D. Nozzle Inspection Annual replacement of
nozzle is recommended. The nozzle size
should match the design load. DO NOT
OVERSIZE. (Determination of oversizing can
be determined prior to your adjustment. If the
firing rate should be reduced refer to Table 4.)
Short cycles and low percent “on” time result
in higher overall pollutant emissions and lower
thermal efficiency. An in-line oil filter will
reduce service problems due to nozzle
clogging.
The filter should be located as close as possible
to the oil burner. Care should be taken to
prevent air leakage in the oil suction line. Use
continuous runs of copper tubing and use
minimum number of joints and fittings.
Always use flare fittings.
E. Adjustment of Electrodes Adjust ignition
electrodes as specified in Figures 13A & 13B.
F. Operate Burner Operate burner, adjust air
setting for good flame by visual observation,
and run for at least 10 minutes or until
operation has stabilized.
G. Check Burner Pressure Bleed air from
pump and nozzle piping. Check pump
pressure and adjust to nameplate pump
pressure, if necessary.
2. COMBUSTION ADJUSTMENT STEPS
H. Set Draft Check the draft reading over the
fire with a draft gauge through a hole in the
inspection door. The hole is above the flame
level. Adjust the barometric draft regulator on
the flue to give the over fire of -.02" W.C.
I. Check Smoke Readings After burner has
been operating 5 or 10 minutes, take a smoke
measurement in the flue, following the smoke
tester instructions. Oily or yellow smoke spots
on the filter paper are usually a sign of
unburned fuel, indicating very poor combustion
(and likely high emissions of carbon monoxide
and unburned hydrocarbons). This condition
can sometimes be caused by too much air, or by
other factors. If this condition cannot be
corrected, major renovation or even burner
replacement may be necessary.
J. Develop Smoke - CO2 Curve Record
measurements of smoke and CO2 from the flue.
Then establish the smoke - CO2 curve by taking
readings over a range of air settings, as shown
in Figure 11.
To do this, start with the air gate set at nearly
full open and then take smoke and CO2
readings at progressively lower air settings, as
necessary to visualize the general shape of the
curve. (The CO2 readings will increase as the
air setting is decreased, unless combustion is
incomplete.) Do not set the air gate to give a
smoke reading above No. 4 or No. 5. Plot the
points on graph paper, as in Figure 11. Usually
3 or 4 readings are enough to establish the
curve.
In adjusting each air setting, it is helpful to note
the various positions of air gate at which
measurements are made so that the final setting
can be located quickly.
K. Adjust Air Setting Examine the smoke - CO2
plot and, keeping in mind the curve of Figure 11,
note the location of the “knee” where the smoke
number begins to rise sharply. Noting the air
gate position marks, adjust the air setting to a
CO2 level 1/2 to 1 percent lower than the CO2
level at the “knee”. (This provides a tolerance
against possible shifts in the setting over a
period of time.) Do not increase the air setting
any more than necessary on the lower portion
of the curve below the “knee”.
The characteristic curve for some burners may
not yield a distinct “knee” in the curve. In such
cases, the setting should be made near the
minimum smoke, (using judgement).
Lock the air adjustment and repeat draft,
CO2 and smoke measurements to make sure
the setting has not shifted.
3. COMBUSTION DIAGNOSIS
L. Check Performance A well-matched and
well-tuned burner should be capable of
operation with smoke not greater than No. 2
and at a CO2 level not less than 10%.
If this cannot be reached, check the following:
Manual
Page
2100-540D
25 of 45
1. Air leaks into the combustion chamber or
heat exchanger can dilute the combustion
gases and prevent normal CO2 readings.
Such leaks should be sealed with furnace
cement or other high-temperature sealant.
To check for dilution by leakage, measure
the CO2 at as high a point as possible over
the fire, using a stainless steel tube
inserted through the fire door sample hole
(as described earlier for overfire draft
measurements), and compare this with the
CO2 measured in the flue. A difference of
more than 1 percent CO2 between the flue
and overfire reading usually indicates air
entry through leaks that have not been
properly sealed.
Seal between the probe and inspection door
sample hole during test. The inspection
door hole should be sealed when not being
used to avoid leakage of air through it.
(See Step H.)
2. If the CO2 level of 10% cannot be reached
without exceeding No. 2 smoke, poor
mixing of air and fuel is likely.
It may be necessary to replace the
combustion head or try different settings.
4. FINAL CHECKS
M. Measure Stack Temperature Operating the
unit at an excessive firing rate will generate
more heat than the heat exchanger can utilize
and result in unnecessary heat loss up the
chimney. Other causes of excessive heat loss
are badly sooted heat exchanger surfaces and
excessive draft. The temperature of the flue gas
provides an indication of these heat losses.
Measure flue temperature by subtracting the
room air temperature from the thermometer
reading. Excessive stack loss is indicated if the
net stack temperature during steady operation
exceeds 600°F.
N. Check Ignition Check operation over repeated
cycles to ensure prompt ignition on starting.
O. Check Pump Cutoff Slow pump cutoff at the
end of a firing cycle can cause smoke and other
pollutant emissions. Check for prompt pump
cutoff by observing flame or by testing smoke
at shutdown. If poor cutoff is observed, make
sure air is purged from the pump and nozzle
line. Air trapped in the pump or nozzle line
will expand when heated, thus causing oil to
drip into the combustion chamber after
shutdown. If poor cutoff persists, repair or
replace pump. Also make sure the pump
solenoid is working - if not replace.

SHORT FORM ADJUSTMENT
PROCEDURE
Some burner service organizations may wish to
perform a shorter procedure for the adjustment of oil
burners. The following is an example of such a short
form prepared by the National Association of Oil Heat
Service Managers.
1. SERVICE AND CLEAN BURNER
Follow company procedure to complete the
cleaning and servicing. Operate burner for ten
minutes while tools are gathered and are cleaned.
2. CHECK DRAFT
Set draft regulator, if necessary. Regulator should
be adjusted to achieve a -.02" W.C. over fire
condition. The more restricted and lengthy the
flue, the higher the draft necessary to obtain the
accepted over fire conditions.
3. SMOKE TEST
Follow the instructions of the manufacturer of the
smoke tester and take a smoke sample. Adjust the
air to obtain a preliminary reading of about No. 3
spot. Then readjust the air to obtain the lowest
possible reading, but do not open the air adjustment
more than absolutely necessary to obtain a trace or
No. 0 spot.
4. CO2 TEST
Check CO2 levels. This level should be between
10% and 12%.

SPACING OF ELECTRODES
COMBUSTION AIR REQUIREMENTS
The electrodes should be spaced 5/32" apart. They
should extend 1/16" beyond the end and 5/16" above the
center of the nozzle tip as shown in Figures 13A & 13B.
This furnace must be installed in a location where a
sufficient supply of combustion air is available for the
complete combustion of the fuel oil. Keep in mind that a
certain amount of excess air is required as well to ensure
complete combustion of the fuel oil.
GUN ASSEMBLY ADJUSTMENT
The gun assembly can be adjusted in the slot inside of
fan housing by loosening screw holding slot cover in
position. Nozzle tip should ordinarily be located 1-1/8"
behind the front face of the cone.
REMOVING GUN ASSEMBLY
Disconnect the oil line at the fan housing and remove
lock nuts on copper tube fitting. Loosen igniter hold
down clamps, then swing igniter up and backward. Gun
assembly can now be removed through this opening.
When structures are constructed too tightly to supply
sufficient combustion air, air from outside the structure
is required to be brought in directly to the furnace. This
furnace has been conveniently designed to accept a
combustion air boot which is attached directly to the
outdoors by means of a 4" pipe. This pipe can be rigid or
flexible, but it is recommended that a metallic material
be used. Refer to Figure 14. The air boot used for this
design is a Field Controls model number CAS-2B-90E
that can be purchased through your local distributor.
Follow all installation procedures as specified in the
instructions packaged with the air boot kit.

APPLIANCES LOCATED IN CONFINED
SPACES
In unconfined spaces in buildings, infiltration may be
adequate to provide air for combustion, ventilation, and
dilution of flue gases. However, in buildings of
unusually tight construction, additional air shall be
provided using the method described under “All Air
From Outdoors” in Figure 16.
An unconfined space (such as an open basement) must
have a minimum volume of 50 cubic feet per 1,000
BTUH of total of all appliances in area. Adjoining
rooms may be counted as one area only if there are not
doors between the rooms.
Shown in Table 8 are the required minimum areas in
square feet to qualify as an unconfined space for
various total BTUH input ratings. The table is based
on a room(s) with 8 foot ceiling heights.
If the unconfined space is within a building having
insufficient air because of tight construction, the air for
combustion and ventilation shall be obtained from
outdoors or from spaces freely communicating with the
outdoors. Under these conditions a permanent opening
or openings have a total free area of not less than one
square inch per 5,000 BTU per hour (28 square inches
per hour ) of total input rating of all appliances shall be
provided. For combustion air options see “Combustion
Air Requirements”.

LOUVERS AND GRILLES
In calculating free area for ventilation and combustion
air requirements, consideration shall be given to the
blocking effect of louvers, grilles, or screens protecting
openings. Screens used shall not be smaller than 1/4
inch (6.3 mm) mesh and shall be readily accessible for
cleaning. If the free area through a design of louver or
grille is known, it shall be used in calculating the size
opening required to provide the free area specified. If
the design and free area is not known, it may be
assumed that wood louvers will have 30-35 percent free
area and metal louvers and grilles will have 60-75
percent free area.
VENTING OPTIONS
This furnace is designed to be vented conventionally
into a vertical chimney or horizontally through a side
wall with an optional Field Controls side wall power
venting system.
Note that the FH, FC and FLF series furnaces have
been designed to allow for bringing the vent system
through the cabinet side for increased venting
flexibility. To take advantage of this feature, simply
remove the desired knockout from either side or top of
unit and rotate flue box accordingly by removing four
(4) screws under cleanout plate as shown in Figure 4.
Make sure smoke pipe gasket is in place before
reinstalling flue box screws.
VERTICAL VENTING
If the unit is to be vertically vented make sure the flue
pipe from the furnace to the chimney is the same size
diameter as the flue outlet of the furnace which is 6".
The flue pipe must have no reductions in diameter, be
made of a corrosion-resistant material having an
upward pitch of 1/4" for every foot of horizontal run,
and be made of material capable of handling
temperatures up to 1800°F.
A barometric damper is supplied with the furnace and
must be installed in the flue pipe observing the
instructions packaged with the damper control. The
barometric damper opening must be located in the same
atmospheric pressure zone as the combustion air inlet to
the furnace. The furnace must not be vented into the
same chimney with any solid fuel burning appliance
such as a wood burner or pellet burner. Masonry
chimneys must be lined with a listed system or other
approved material that will resist corrosion, softening
or cracking from flue gas temperatures up to 1800°F.
See Standard for Installation of Oil Burning Equipment
NFPA31 latest edition and Standard for Chimneys
NFPA211 latest edition for additional information.
HORIZONTAL VENTING
This furnace is designed to be horizontally vented
through a side wall with an optional side wall power
vent. The recommended side wall vent is the Field
Controls model number SWG-4HDS for 085 and 110
models, and SWG-5S for 140 models only. This vent
can be purchased through your local distributor.
Follow all installation instructions packaged with the
vented system.
THERMOSTAT
These furnaces are designed to be controlled with any
24V heating or heating/cooling thermostat. The
heat/cool thermostats must be designed for independent
heat/cool transformer circuits to assure that the 24V
transformer built into the oil primary control does not
conflict with the main furnace 24V transformer. The
heat anticipator should be set at 0.20A. This is a
nominal setting. The thermostat circuit should be
checked to verify setting.

MAINTENANCE
LUBRICATION
No lubrication is required for either the burner or the
blower motor. Both are permanently lubricated.
INSPECT AIR FILTER
Replace filters before each heating season begins. It is
recommended that filters also be replaced at least twice
during the heating season.
Be sure the new filters are set securely in the filter rack
so there can be minimal leakage around them.
FINAL INSPECTION AND TEST
Final inspection and test of an installation shall be
made to determine that the work has been done in full
accordance with regulations and according to the
highest standards for safety, performance and
appearance. Such an inspection and test should
indicate the following as a minimum:
1. Determine that all parts of the oil storage and
circulating system, including tank, piping and
burner, are free from oil leaks. Be sure that no oil
discharges from the nozzle when burner is not
operating.
2. Be sure that the suction line and pump have been
entirely vented of air so that the burner has
instantaneous oil shutoff at the nozzle and so that
the pump operates without an air noise.
3. Check the flame adjustment to determine that the
flame is clear, quiet, free of odor and oil nozzle is
of proper size for the furnace.
4. Test operation of burner by operating the
thermostat. First, set the thermostat above room
temperature. Burner should start. Second, set
thermostat below room temperature. Burner will
stop.
5. Check operation of burner primary control in
accordance with manufacturer’s instructions
included with the control. Following is the method
we recommend in checking the safety switch in
this primary control.
A. Flame Failure – Simulate by shutting off oil
supply manual valve while burner is on.
Within 9 seconds the control will shut the
burner down and flash a diagnostic code of
1/2 second on / 1/2 second off. Ignition and
motor stop and oil valve closes.
B. Ignition Failure – Test by closing oil supply
while burner is off. Run through starting
procedure. The primary control will attempt
three trials for ignition. After three attempts,
the control will lockout.
C. Power Failure – Turn off power supply
while burner is on. When burner goes out,
restore power and burner will restart.
D. If operation is not as described, check wiring
and installation first. If trouble appears to be
in the control circuit, replace the flame
detector. If trouble still persists, refer to
“Common Causes of Trouble” section.
SERVICE HINTS
Preventive maintenance is the best way to avoid
unnecessary expense, inconvenience, and retain
operating efficiency of your furnace. It is advisable to
have your heating system and burner inspected at
periodic intervals by a qualified serviceman. If trouble
develops, follow these simple checks before calling the
serviceman.
1. Make sure there is oil in tank and valve is open.
2. Make sure thermostat is set above room
temperature.
3. Make sure electrical supply to furnace is on and
fuses are not blown or circuit breakers tripped.
4. Reset safety switch of burner primary control.
CAUTION
Reset three (3) times only. More than three
resets can cause excessive oil to be pumped
into combustion chamber which could result
in explosion upon ignition.
5. Make sure air filters are in place and are clean.
6. Make sure all air openings in furnace, all
ventilation and combustion air openings, all return
air grilles, and all warm air registers are
unobstructed and open.

COMBINATION COMBUSTION
CHAMBER/BURNER MOUNTING
SYSTEM
The furnace has been designed with a combustion
chamber mounting system that enables service
personnel to remove the combustion chamber, its
mounting system, and burner assembly as one unit for
inspection and/or service on the bench. It has also been
designed to remove the burner assembly independently
from the mounting system to perform basic annual
service and inspection. The mounting system is
completely adjustable so exact alignment between the
burner tube and combustion chamber may be assured
prior to installation into the furnace. See Figures 22
and 23.
WARNING
The procedures described in Figures 22 & 23
should be conducted only by a qualified
service technician.
Improper servicing could cause electric shock
hazard, fires or explosion resulting in damage,
injury or death.

COMMON CAUSES OF TROUBLE
CAUTION
To avoid accidents, always open main switch
(OFF position) when servicing the burner.
BURNER WILL NOT PRODUCE FLAME
Check oil level gauge to see that there is sufficient oil
in tank or tanks. Check the burner mounted relay
control. Do not adjust this control.
Check position of electrodes – incorrect position will
cause slow or delayed ignition. Clean electrodes and
nozzle. Check and clean strainer in pump. If oil line
filter is used, check filter condition.
If burner runs but there is no flame the fuel pump may
be air bound. Follow instructions for bleeding fuel
pump.
PUMP SQUEALS OR CHATTERS
This may be caused by air in pipes. Check all joints in
the oil supply pipe for leaks. Check strainer in pump; if
dirty, clean.
INSUFFICIENT HEAT
Check limit control setting. It may be that flame is not
allowed to stay on long enough to generate sufficient
heat in furnace to heat the house properly. If the proper
size furnace has been selected according to house
requirements and satisfactory heat is not obtained,
recheck the heating plant for size and capacity in
relation to house. Check for clogged filters.
Check and make sure the heat anticipator on the
thermostat is set correctly.
CARE OF FINISH
This furnace cabinet is made with a very durable and
corrosion resistant finish. With normal cleaning it will
last for many years.
Check and make sure the solenoid valve on the oil
pump is being energized and opening.
BURNER STARTS OR STOPS TOO OFTEN
Check heat anticipator setting on thermostat.
NOZZLE PRODUCES A STRINGY FLAME
Worn tangential grooves in nozzle. Replace nozzle.
BASEMENT TANK HUM
Occasionally with a two-pipe installation there may be
a low return line hum. Eliminate hum by installing a
special anti-hum valve in the return line near pump.
HEAVY FIRE OR PULSATING FLAME.
These may occur after burner starts. It may be caused
by a slight oil leak in the fuel pump and cannot be
corrected except by replacing the pump. This happens
only when the burner is started.
CHATTERING SOUND OR HIGH PITCH NOISE
This noise from motor can usually be traced to where a
conduit or BX cable is fixed rigidly or attached to some
part of the building. Relieving this strain may eliminate
noise.
Manual 2100-540D
Page
42 of 45
WARNING
Under no circumstance should a soot
deterioration device be used in the
combustion chamber. These products known
as “soot busters” or “soot sticks” are
comprised of chemicals that burn at very high
temperatures, which may exceed the
temperature rating of the combustion
chamber material.
Use of these products are detrimental to the
life expectancy of the combustion chamber
and will destroy the chamber. Refer to the
“Cleaning of Furnace” section for proper
cleaning methods.
CLEANING OF THE HEAT EXCHANGER
All of these units have four clean out plugs for easy
cleaning of the heat exchanger. They are accessible
from the front and back of these units by removing the
clean out access cover in the burner compartment and at
the back of unit. The furnace should be checked
annually by a qualified service technician.
